Hydrothermal synthesis, crystal structure and electrochemical properties of the complex [Co(phen)2(m-chlorobenzoic acid)2•(H2O)] • (H2O)2

The title complex has been synthesized with m-chlorobenzoic acid, 1,10-phenanthroline and cobalt perchlorate anhydrous in the solvent mixture of water and methanol. Crystal data for this complex: triclinic, space group P (1) over bar, a=0.8707(3) nm, b=1.2844(4) nm, c=1.6929(5) nm; alpha=75.430(5)degrees, beta=77.562(5)degrees, y=86.346(5)degrees, V=1.7894(9) nm(3), D-c=1.456 g(.)cm(-3), Z=2, F(000)=806. Final GooF=1.065, R-1=0.068 4, wR(2)=0.1275. The crystal structure shows that the Cobaly ion is coordinated with four nitrogen atoms from two 1,10-phenanthroline molecules and two oxygen atoms from one m-chlorobenzoic acid molecule and one water molecule respectively, forming a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex is also reported.
